短文改错（共10小题，每小题1分，满分10分）
For most people, it is almost impossible to operate on a computer without a mouse, let alone surf the Internet. A well-chosen mouse is really handy, flexible and convenience in controlling the screen. Without the functions of inserting, deleting, moving and copying, it enables us to edit text, browse web pages and download that we want. It can even bring us a flood of musics, movies and PC games. Just imagining, all that can be done with a cute mouse.
A convenient tool can certain make our work easier, and it doesn’t always help in a positive way. Too much ready information on our fingertips leaves a little room for knowledge pursuing. Too many ready answers make us less excited in finding truth. Relying too much on mouse clicking make us much lazier and less creative.
